Personal finance webapp Mint.com has graduated from beta development and now offers a variety of new features. Prior to leaving beta only a small number of test users had access to the investment tracking features. Now all users are able to track investment vehicles such as IRA, 401k, and 529 accounts. The 401k section has been enhanced and now includes support for tracking past and present 401k accounts. The most prominent change is the one users requested the most: the ability to define their own transaction categories instead of relying on the predefined categories supplied by Mint. For more information about Mint, check out our screenshot tour from earlier this year.
